How often does this happen? Every time? Is there anything else in the logs that might give us more information? Are you using certificate-based or token-based authentication?

Hi Jon,

Thanks for your reply. To answer your questions. This issue is happening everytime and following is the exception stacktrace that we are getting

Also We are using certificate based authentication 

[Jon Chambers]

Thanks for sending the full stack trace, but that wasn't quite what I was looking for. Is there a message in the logs NEAR the stack trace that gives any hints as to why the connection may have closed?

If you're using certificate authentication, are you positive you're using the right certificate?

Dear Jon,

Thanks for your reply. We are using the correct certificate as the same code works perfectly fine on windows operating system and we are able to trigger push notifications.

Dear All,

The issue is now resolved.

following steps were done to resolve the same

1) configure proxy setting in the code using httpproxyhandlerfactory as shown below

new ApnsClientBuilder().setApnsServer(ApnsClientBuilder.DEVELOPMENT_APNS_HOST).setClientCredentials((File) certInfo.get(0), (String) certInfo.get(1)).setProxyHandlerFactory(new HttpProxyHandlerFactory(new InetSocketAddress("10.10.12.10", 8080))).build();

2) Have following jars in the classpath

      netty-all-4.1.24.Final.jar

      netty-tcnative-boringssl-static-2.0.8.Final-linux-x86_64.jar
      pushy-0.13.2.jar 

      fast-uuid-0.1.jar

[Jon Chambers]

I'm glad you've resolved the problem.

For future readers, please note that configuring a proxy is NOT a universal solution to this problem. If you don't know that you have a proxy, definitely don't add a proxy handler to your client.
